摘　　要：目前教育网日益发展,校园网建设也越来越普及,校园网用户访问公众网采用双出口技术日臻成熟,基本解决了访问公众网资源慢的问题,但公众网访问校园网资源慢的问题还比较突出,原因是服务器没有实现双出口技术。本文研究了目前较流行的服务器双出口方案的实现,指出了它们的优缺点,详细讨论了基于Linux服务器双出口的实现,并给出了实例,结果证明,系统运行稳定,性能会更加优良。The 20th century has witnessed the rapid development in the information technology,including that in education network. Promoted by the development in education network, campus network construction has been increasingly popularized. As a result, technology to realize network dual-export for users is getting more mature day by day. It has basically resolved the problem of slow access. However,it is still a prominent problem for off-campus users to quickly get access to the campus network because technology of dual-export isn＇t adopted in the server system. This paper is devoted to a systematic study of the popular dual-export method in recent years, pointing out its advantages and disadvantages. Then it discusses in detail the realization of dual-export technology which is based on Linux Server, and gives an example, the result proves, the system runs steadily, performance will be finer.
